README
Scuttle - A Multi-Objective MaxSAT Solver in Rust
Scuttle is a multi-objective MaxSAT solver written in Rust and based on the RustSAT library and the CaDiCaL SAT solver.
Publications
This solver was used in the following publications. For each publication, a tag (specified in brackets) marks the exact revision used:
- CP'23 (
cp23): "Preprocessing in SAT-Based Multi-Objective Combinatorial Optimization" [5]. Additional material here. - CPAIOR'24 (
cpaior24): "Core Boosting in SAT-Based Multi-Objective Optimization" [6]. Additional material incpaior24/. - TACAS'25 (
tacas25): "Certifying Pareto-Optimality in Multi-Objective Maximum Satisfiability" [7]. Additional material intacas25/.
Algorithms
| First argument | Description |
|---|---|
p-minimal |
P-Minimal model enumeration as described in [1] and [2] |
lower-bounding |
Lower-bounding search as described in [3] (called "core-guided" there) |
bioptsat |
Sat-Unsat variant of the BiOptSat algorithm described in [4] |
Building
Note: Scuttle requires nightly Rust, which can be installed via rustup.
If you simply want a binary of the solver, you can install it from
crates.io by running cargo +nightly install --locked scuttle.
To build the project from source, make sure to initialize the git submodules
with git submodule update --init --recursive. You can then build scuttle by
running cargo +nightly build.
By default, MaxPre preprocessing is not included in the build anymore. To
include preprocessing with MaxPre, add --features=maxpre.
Features
sol-tightening: includes heuristic tightening of solutions after they are found in the buildmaxpre: includes preprocessing with MaxPre in the build
What's The Name
Apparently "scuttle" is one of multiple term for a group of crabs, which seemed fitting for a multi-objective solver in Rust.
